To all whom t may concern."

Be it known that I, Jo-HN F. WHITE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had therein to the accompanying' drawing.

This invention relates to an improvement in locking means for doors and is designed moreparticularly for use in connection with doors for automobiles or carriages.

The invention appertains to that type of lock wherein a pivoted locking bolt is employed which is manually operated, both to locking and unlocking position.

The object of the invention is that of providing the bolt with spring actuated means for progressively advancing the locking face of the vbolt into locked or engaged position with the keeper on the door jamb and for locking or maintaining it in such position against rattling or backward deflection.

Locks for doors for carriages and wagons are subject to the variations of the material upon which they are mounted caused by difference in temperature or swelling and locks which are provided with means for holding the locking element in a fixed or single position are objectionable inasmuch as there is no means provided for taking up automatically the loose fit or providing for the variable conditions suggested. The present invention comprehends a lock fastener or securing `mechanism which will maintain the locking face of the bolt in close contact with the engaging face of the frame of the keeper,

and so irrespective of the variations caused by temperature conditions or wear.- Other advantages of the construction presently to be described will be readily appreciated.

In the drawings there is shown a convenient and desirable form `of lock having the different advantageous characteristics,

but it is to be understood that in addition to the modifications of operating means shown other means may be employed without departingA from the general nature and principle of the invention. e

In the drawings: I Figure 1 is a sectional view of the improvement showing the rocking locking bolt in its position for securing the doorsclosed;

Fig. 2 is a section showing parts in elevation of means for operating the bolt securing means from either side of the door;

Fig. 3 is an elevation of the inside operating means shown in Fig. 2;

gig. 7 is a detail perspective of the keeper, an

Fig. 8 is a section through the lock showing the preferred form of instrumentalities for operating the lock to set and maintain the same in its proper locked position.

The lock presently to be described is de-` signed more particularly for use in automobile doors and in the drawing the door part is designated by the letter A While the frame or jambb part is designated by the letter B. The jamb part is provided with a recess b and a keeper plate b secured to the face of the jamb and having thereon intermediate its ends vthe bolt engaging part B2. rIhis part is conveniently formed of metal and has its intermediate portions bulged or crowned, as at b2. It occupies when in position the rear part of the mortised or grooved out portion b of the jamb and is designed to receive thrusts of the locking bolt presently to `be described.

The `door A is mortised to receive a lock, frame C in which is pivotally mounted a rocking bolt D having as usual in such types of boltsna curved face for entering through an opening in the -frame and having a tail piece d opposite the locking face el. 4The bolt is formed conveniently with a substantially straight rear face, as at d2 in which is formed a tapered-groovev da. This groove terminates on a plane below the pivot of the bolt, as shown in Fig. 8. In the curved face of the bolt there is provided a substantially tl-shaped notch d4 in advance of the tapered groove d3.' Y

Mounted on a vertically disposed shaft Ejournaled in the opposite side walls of the housing C is a setting and securing arm F for the pivot locking bolt. 'Ihe end of the arm F is projected into the groove d3 of the locking bolt, as shown in Fig. 8, and

with the` part B2 of the keeper.

as shown in said ligure, by a spring F, the latter engaging the outer face ofthe arm and being coiled around the shaft E,-

asshown in Fig. -5. The tendency of the spring is to carry the end of the arm into positive engagement with the straight surface'at the bottom of the groove d3 of the `locking bolt ,and thereby force the locking tive engagement and results in an antirattler being provided and maintains the two locking surfaces in positive engagement at all times. To permit the door to be opened it is only necessary to move the shaft E downward.

With this in view the lower end of the shaft is provided with a diagonal groove or camwayv c in which a pin e on the hub of' thedarm F loosely plays. `The shaft is held against rotation by means of a pin E slidably mounted in suitable sockets E2' on the upper face of the door frame. The shaft is provided with an operating head G and is surrounded at its lower end by a spring Gr abutting a shoulder or collar on the `shaft at one end and the lock housing at the other end. Thel shaft has a free play up and down. By virtue of the cam e, the agrm F -is rotated so as to carry itspoint into er out of engagement with the rocking bolt. The

construction described is clearly 'depictedj in Figs. 5 and 8. In these gures it will be Fig. 8.-

noted that the V-shaped notch dtlis so vpositioned thatas'the end of the'arm `F engages the rear wall of the notch the arm operating spring F will tend to force the point of the lbolt into the housing and there retain the saine, as shown .in' dotted lines,

As a modified. formof structure there is shown in Fig. 1 alock bolt H having a straight rear face n h. There is a rocking bolt lock I having its end part arranged j liXedly on a vertically arranged shaft j mounted in the casing. The shaft y' is arranged outwardly beyond the plane of the pivot for the-bolt 'I-I and is so proportioned that upon the-rocking, of the part I outward it will engage the fiat surface of vthe bolt and cause lits lock point to engage lthe keeper.

The point'l of contact between the part I and the bolt will vary according to the positions of the locking part thereof and the keeper, the arm being so con-y vstructedvv as to'advance and` take up any wear 'or variations that may eXlst.` To secure this result a spring is associated with the shaft j and tends to at all times maintain the same in its outward position, as shown in Fig. 1. A convenient form of spring 4may be that shown in Fig. `2 wherein a reciprocating handle shank L is shown mounted in the door and surrounded by a coiled spring Z. This shank is provided with a handle Z which may be drawn out and in its movement operates a bell crank M rigid on the shaft. The spring normally tends to ymove the shaft in the position shown in full lines, Fig. 2. The bell crank is also provided with an arm N having a finger piece N on its outer end whereby the shaft 7' may be rocked from the inside through the finger piece, as well as from the outside of the door from the handlel. When the bolt H of the construction shown in Fig. 1 is yfully withdrawn it is engaged by a small spring actuated friction pin O seated in the rbolt and adapted with its outer end to engage a recess O in the wall of the lock casing. This will hold the bolt in open position against the tension of the spring Z to force the same into closed position.

In Fig. 6 a slightly modified form of operating means is shown wherein the shaft .E has a cross arm P thereon, one end of which is provided with a thumb piece p while the other end is loosely connected with a reciprocating thumb piece Q mounted in a suitable bearing on the outery face of the door. The thumb piece Q has a stem entering a perforation in the door and below the saine is provided a spring R which servesto rock the cross head in the position shown in Fig. 6 and the locking arm in position to lock the bolt closed. This construction enables the operation ofthe latch asI struction whereby la beveled gears is mounted on the top of the shaft E., the latter being normally rotatedA in one' direction by a spring S. To* turn the shaft a comple- -mentary beveled gear S2 is employed mounted on a contershaft or spindle T\'passing through the door. The opposite ends of the fspindle' are provided with handles T.

' By the above described construction, including the modified forms, it'will be ascertained that the locking bolt is always set into close contact with'the keeper and there held. It will .be observed further that upon the actuation or' the handle or the operating part the arm will be released and the bolt can thereby be readily set back into unlocking position u on the opening of the door. Inasmuch as t e spring arm is always in contact with the bolt, as soon as the dooris closed the bolt being driven into` locked position, the end of the spring arm following up the movement of the bolt will sustain it' any play between the bolt and its keeper, the-130 mames arm will advance and progressively take up such play or movement. The device may be very properly characterized as an anti-` rattler. v

The arc through which the securing arm moves is so .related to the arc through which the pivoted bolt moves that the former will exert a pressure in the direction of closing or locking of the bolt a-t all times and even beyond a straight or right angular position with relation to the keeper.

ln the broader aspect of the case the invention may be carried out with 'the single spring, as suggested, in the modified forms, as well as the two springs suggested in the construction shown in Figs. 5 and 8. The swinging action' of the securing arm with its operative end arranged to engage the bolt is an important feature of this invention.
